* The PENTA burner not only looks different, it burns different with lava rock & especially with glass media. It is designed to deliver a very uniform & full flame form edge-to-edge – a dramatically different look than the conventional high-center flame given by standard fire rings. This is accomplished by utilizing holes drilled at the 3, 9, & 12 o’clock positions of the stainless steel tubing for a broader flame. If you enjoy your flame on low, this will not exhibit the ring pattern seen with some concentric fire rings. The burner uses HPC’s raised hub design to shed water and is low profile requiring less media. HPC suggests that their products be installed by professionals that are locally licensed by the authority having jurisdiction in gas piping.”
